On the hardest jet, i.e. the jet with the largest transverse
momentum \(p_{T, \text{jet}}\) , we measure the
angularities [1]}, [2]}, [3]}
\(\lambda _\alpha ^\kappa = \sum _{i \in \text{jet}}\mathopen {}\mathclose {\left(\frac{p_{T,i}}{\sum _{j \in \text{jet}} p_{T,j}}\right)}^\kappa \mathopen {}\mathclose {\left(\frac{\Delta _i}{R_0} \right)}^\alpha \,,\)
